TYPE-WRITING MACHINE.

Specification of Letters Patent.

Patented Feb. 5, 1907.

Original application filed July 6, 1904, Serial No. 216.526. Divided andthis application filed October 11, 1904. Serial No. 227,997.

To u/hmrb it many concern:

Be it known that I, CHARLES PmLo MOsHER, a citizen of the United States,and a resident of Syracuse, in the county of Onondaga and State of NewYork, have invented certain new and useful Improvements in Type-WhitingMachines, of which the following is a specification.

My invention relates to type-writing maro chines, and more especially totabulating and carriage-stop mechanism for such machines,- and theobject of this invention is to provide improved devices of the sortspecified.

The present improvements are more especially useful in connection with awide-carriage machine, and the invention is here shown applied to aMonarch type-writer having wide carriage.

The invention includes novel supports for 20 the carriage-rails, so asto accommodate a long tabulator-bar for use in connection with the widecarriage. There are also novel features in the manner in which thetabulatorbar is mounted in the framework of the machine and in themechanism by which said bar is operated. There are also novel featuresin the mechanism whereby the marginstop bar is operated to release thecarriage from the margin-stops.

My invention consists in various features of construction andcombinations and arrangements of parts, all as will be hereinafter morefully described, and particularly pointed out in the claims.

The present application is a division of my application, Serial No.215,526, filed July 6, l 904.

One embodiment of my invention is illustrated in detail in theaccompanying drawings, in which Figure 1 is an end elevation of atype-writing machine. Fig. 2 is a front to rear sectional view of thesame. Fig. 3 is a detail view, in rear elevation, partly, in section;and Fig. 4 is a view of the machine in rear elevation.

I have shown my invention applied to the Monarch front-striketype-writer. The main frame of this machine comprises a base portion 1,from which rise posts 2, which support a top plate 3. Keys are mountedon the ends of key-levers, which are pivoted near the back of themachine and which operate upwardly and rearwardly, striking typebarswhich carry types which strike against the front face of the platen 5.This mechanism is well known, and it has not been thought necesssary toshow it in the present case. A carriage truck 6 has raceways formed inits upper and lower edges, and said truck is supported by antifrictionballs or rollers 7, which run in said raceways and in cooperating racewafs formed in a lower fixed rail 8 and an upper fixed rail 9. As shown,for example, in Fig. 4, the length of these rails exceeds the width ofthe main frame, and said rails are accordingly supported at pointsintermediate their ends by two brackets 10, which are secured to the topplate of the machine by screws 11, Fig. 2. In the present instance thesebrackets are shown formed with a U-shaped cross-section for the sake oflightness and stiffness. The lower rail 8 is secured to the brackets byscrews 12, Fig. 4, passing through said brackets and threaded into saidrails. The upper rail 9 has two brackets 13 secured thereon. Thesebrackets are rigidly secured to the brackets 10 by screws 16, Figs. 3and 4, which pass through said brackets 10 and are threaded into saidbrackets 13. Each pair of brackets 1.0 and 13 constitutes, in effect, asingle bracket rising from the top plate 3 and supporting the upper rail9. This compound bracket has the arched or looped form shown in thedrawings for a purpose which will appear hereinafter. The rails 8 and 9are connected together near each end by a bracket or frame piece 17,which projects back from the rear surfaces of said rails, to which it issecured by screws 18, passing through ears 19 of said frame-piece andthreaded into said rails. The carriage-truck 6 may be drawn across themachine by the usual spring-drum and connections or by any suitablemeans.

Two brackets 20 project from the truck 6 toward the front of themachine, one of said brackets being near each end of said truck. Afeed-rack 21, which lies back of the truck, is rigidly mounted at itsends on arm 22, 22, which are pivoted on headed and shouldered screws23, which are threaded into said brackets 20. The arms 22 normally reston stop-pins 24, against which they are pressed by the weight of theparts and also by the tension of a spring orsprings 25, Fig. 4. I

have shown two such springs, each of which passes over a screw 26,threaded into the truck 6 and under a pin 27 on said truck, and whichpresses at its free end on the rack-bar. The rack-bar 21 is gears d to apinion 23, fixed on a shaft 29, which is journale d in the framework,and which has mounted thereon an escapement-wheel 30, which iscontrolled by escapement-dogs. (Not shown.)

I have made certain changes in the tabulator mechanism in order to adaptit to this machine, in which a long platen is used. A stop 94, Fig. 4,is secured to the rear face of the truck 6 and coijperates with a stopor stops 95, Fig. 2, which is mounted on an oscillatory tabulator-bar 96in the usual manner. This bar has notches or slots cut in its surface aletter-space distance apart, and any one of the stops 95 maybe set inany one of these notches. So far as my invention is concerned thecolumn-stops may be of any desired construction. The column-stop bar 96and the column-stops shown in the present instance are like thosedescribed in the patent to Gabrielson, No. 784,317, March 7, 1905. Thestop 95 is normally out of the path of the stop 94, but may be movedinto the path of said stop by rocking the bar 96 toward the front of themachine. The bar 96 is mounted at or near its ends on the brackets 17 ina manner best shown in Fig. 3, which is a rear view of this portion ofthe mechanism. At its rightdrand end the rod 96 passes loosely throughan opening in one of the brackets 17, and at its left-hand end said baris formed with. a central longitudinal opening 98, which fits looselyover a rod or pin 99, which is enlarged at its outer end, forming anannular shoulder 100, against which the end of the bar 96 normallystands. The enlarged portion of the rod 99 is threaded through theleft-hand bracket 17 and is formed at its end with a milled head 101.The bar 96 may be adjusted lengthwise by turning said milled head, thusadjusting the position of the pin 99, which is secured in adjustedposition by tightening a lock-nut 102. It is of course necessary that nostationary part of the mechanism shall stand between the bar 96 and thetruck, and it is for this reason that the brackets 10 have the arched orlooped form shown in the drawings, so that the bar 96 may lie betweensaid brackets and said truck. The bar 96 thus passes tlirough a sort-ofopening in the framework, and it may happen that it is desired to adjustone of the steps 95 to a position within this opening behind one of thebrackets 10, as shown in Fig. 3. Of course the precise form or contourof the bracket is not material so long as it provides the openingreferred to. Where the term arched occurs in the claims, it is to beunderstood that the claims are not to be limited to the use of bracketswherein the openings are formed or bounded by curves. To facilitate thisadadjustment of the stops, the bar 96 is so mount: d that it may bemoved endwise, so as to bring the portions thereof which normally liebeneath the brackets to accessible positions. The pin 99 is made of alength sufficient to permit of such motion. The opening 98 in the bar 96is formed near the end of said bar with an annular groove or enlargement103, into which extends the curved end of a spring 104, which lies in alongitudinal slot formed for the purpose in the pin 99. Said spring issecured in position by a screw 105, threaded into said pin and engagingsaid spring. The rocking mo tion of the bar 96 is controlled by an arm106, Fig. 1, the hub 107 of which, Fig. 3, is mounted on said rod justoutside the righthand bracket 17. In order to permit of the longitudinalmotion of the tabulator-bar above referred to, the hub 107 is looselymounted on said bar and is connected thereto by a pin or screw 108,which is threaded into said hub, and the inner end of which projectsinto a longitudinal slot 109 in the bar, so that the hub and bar areconstrained to turn together. The longitudinal motion of the bar 96toward the right is limited by the engagement of the screw 108 with theend of the slot 109. In order to prevent the hub 107 from moving awayfrom the bracket 17, said hub is formed with a peripheral groove 110,into which projects the head of a screw 111. which is threaded into saidbracket.

The rocking motion of the bar 96 is con trolled by a tabulator-key 112,Fig. 2, which is monnted on the end of a key-lever 113, which is pivotedat its rear end at 114. A pin 115 projects from one side of saidkeylever into a slot 116 in an car 117 of a lever 118, the front end ofwhich is pivoted at 119 to a bracket depending from a portion of themain frame. The lever 118 is connected at its rear end to the lower endof a link 120, which passes loosely through an opening in the back shelf121 of the main frame and eX- tends above the top plate 3. The link 120has a collar 122 fixed thereon by a set-screw 123, Fig 2, and acoiledspring 124, com pressed between said collar and the shelf 1.21, holdssaid link in its normal position. Projecting from the collar 122 towardthe front of the machine is an arm 125, which stands above a lever 126,so that when the tab'ulatorkey is depressed said arm depresses saidlever, which operates a release device which raises the feed-rack out ofengagement with its pinion. This release device is old and well knownand is not shown herein. As best shown in Figs. 2 and 4, the link 120 ispivoted at its upper end to the free end of an arm 127, which is fixedto and projects toward the back of the machine from a rockshaft 128,which is journaled at one end in an opening in one of the brackets 10and at the other in one of the brackets 17. An arm 130, Fig. 1, is fixedonthe outside end of the shaft 128, and said arm is connected by a link131 with the arm 106, which is mounted on the tabulator-bar 96, Theconstruction is such that if the tabulator-key be depressed the link 120will be drawn downward, the shaft 128 will be rocked toward the back ofthe re achine, and the tabulator-bar 96 will be rocked toward the frontof the machine, bringing the tabulator-stop into the path of thecarriage-stop, the lever 126 releasing the carriage from the escapernentmechanism. It will be perceived that the rock-shaft 128 has beeninterposed in the connections between the tabulator-ke and thetabulator-bar in order to carry such connections out to the end of thelong tabulatorbar used in this machine.

The margin-stops are mounted on an oscillatory bar 132, which is journaled in brackets 133, rising from the top stationary rail 9. Thisbar does not differ materially from the bar ordinarily used in theMonarch typewriter, except in that it is longer and the connectionsbetween said bar and the carriagerelease key have been extended out toits end in a manner somewhat similar to those of the tabulator key andbar. The margin-stop bar has projecting from one end thereof to ward theback of the machine an arm 134, Fig. 1, having a pin 135, which works ina slot 136 in the upper end of a link 137, the lower end of which ispivoted at 138, Fig. 2, to an arm 139, Fig. 4, of a yoke-frame 140,which is journaled on the rock-shaft 128. The yoke-frame 140 extendsbeyond the arm 127 of said rock-shaft and at its inner end has arearwardly-projeating arr-i 141, Fig. 2, which is connected by a link142 to the rearwardlj "-extending arm of a bell-crank lever 143, whichis pivoted on a shouldered and headed screw 144, which is threaded intoa bracket 145, secured to one of the rear posts of the main frame byscrews 146, threaded into ears 147 of said post. Saidrearwardlyextending arm of the bell-crank 143 is normally drawn againsta stop-pin 148, projecting from the bracket 145, by a coiled spring 149,which is connected at one end to said stop-pin and at the other end to abracket 150, depending from said bell-crank. Said bellcrank has anupwardly-extending arm, to which is pivoted a push rod or bar 151, whichextends to the front of the machine and has a margin-release key 152,mounted on its front end. The forward end of the bar 151 is guided by anopening in a frame-piece 153, through which said bar loosely passes. Theconstruction is such that if the releasekey 152 be pushed toward theback of the machine the bell-crank 143 will be rocked, the link 1 42will draw the arm 141 downward, rocking the yoke-frame 140 toward theback of the machine, thus pulling down the link 137 and rocking thestop-bar 132 toward the back of the machine. This motion of the stop-barpermits the margin-stop to pass the cooperating stop on the framework ina manner which is old and well known. Said stop-bar is provided With theusual returning spring 154 and finger-buttons 155.

It will be observed that the brackets which support the stationarycarriage-rails are arched away from the carriage in order to accommodatethe tabulator devices, that the column stop-bar is situated within thearches of said brackets, and that the stop 94 on the carriage movesthrough the arches of said brackets during the traverse of the carriage.

Various changes in the details of construction and arrangement may bemade without departing from the gist of my several improvernents.
